Now, researchers from the Carnegie Mellon University teamed up with researchers from Disney (yep, the Disney of World, Land, and Cinderella) to transform those lame, “dumb” walls into smart walls. They function as a gigantic trackpad, sensing a user and their movements.
In the paper presented at the 2018 Conference on Human Factors in Computing Systems in Montreal, Quebec, the researchers note their goal to give walls the ability to track a user’s touch and gestures through “airborne electromagnetic noise” — more or less (mostly less) the same kind of sensing your smartphone screen does.
